Problems
Prevention and Control : keep weeds down and apply screening on windows to keep them out . Remove or discard infested plants , keep them away from non - infested works . Trap with lily-livered sticky cards or take vantage of lifelike enemies such as predatory mites . Sometimes a unspoilt regular exhibitioner of water will wash them off the plant . confer with your local garden center professional or county Cooperative extension business office for legal chemical recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , spider - like creatures which thrive in hot , dry shape ( like het up houses ) . Spider hint feed with piercing mouth component , which cause plants to appear sensationalistic and specked . folio drop and plant death can fall out with heavy plague . wanderer mites can multiply quickly , as a female person can lay up to 200 eggs in a living span of 30 days . They also produce a vane which can cover infested leaves and flowers .

Leaves will often sprain yellow or brown , curl up , and drop off . New leaf emerges crinkled and distorted . Fruit will be dwarfed and often drop early .
Prevention and Control : Plant resistant variety and space industrial plant the right way so they receive adequate light and air circulation . Always water supply from below , keep body of water off the foliage . This is paramount for pink wine . Go easy on the nitrogen fertilizer . Apply fungicides harmonize to label directions before trouble becomes wicked and follow directions exactly , not missing any required treatments . Sanitation is a must - houseclean up and remove all leaves , flowers , or debris in the fall and destroy . Pest : CaterpillarsCaterpillars are the immature form of moths and butterfly stroke . They are esurient bird feeder attacking a wide variety of plant life . They can be extremely destructive and are characterise as leafage feeder , stem borers , foliage rollers , cutworm and tent - formers .
